The X-Parasite is the primary antagonist and a unique gameplay mechanic. When you defeat an enemy, it releases an X-Parasite. Absorb these to regain Energy and Missiles. Different colored X-Parasites grant different benefits: yellow for Energy, green for Missiles, and red for a full refill of both. Be careful, as unabsorbed X-Parasites can re-animate defeated enemies or transform into more dangerous forms. Your Fusion Suit is immune to their direct harm, but their hosts are not.
